[Matlisp-users] (use-package "MATLISP") doesn't work

[Tamas K P. <tp...@Pr...>]

I start cmucl (latest version) and do (load "start.lisp") from the
directory where I put matlisp.

I try to load it with use-package, but get the following error message:

*  (use-package "MATLISP")


Error in function USE-PACKAGE:
   Use'ing package MATLISP results in name conflicts for these symbols:
(REAL HELP)
   [Condition of type SIMPLE-ERROR]

Restarts:
  0: [CONTINUE] Unintern the conflicting symbols in the COMMON-LISP-USER package.
  1: [ABORT   ] Return to Top-Level.

Debug  (type H for help)

(USE-PACKAGE "MATLISP"
             #<The COMMON-LISP-USER package, 8/9 internal, 0/9 external>)
Source: Error finding source:
Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no longer exists:
  target:code/package.lisp.
0]


OTOH, in-package works fine:


* (in-package "MATLISP-USER")

#<The MATLISP-USER package, 1/9 internal, 0/2 external>

but only after I run (load "start.lisp").

Questions:
1. do I need to load start.lisp every time I want to use matlisp?
2. how can I make use-package work?

Sorry if the question is dumb, I am new to Lisp.

Thanks,

Tamas
